Intermolecular compounds of fatty acid triglycerides

Abstract

There are provided an intermolecular compound of (a) di-saturated medium chain fatty acids mono-saturated long chain fatty acid triglyceride and (b) 1,3-di-saturated long chain fatty acids 2-mono-unsaturated long chain fatty acid triglyceride, of which a long spacing value by X-ray diffraction is 65 Å or more, and foods containing the intermolecular compound. The intermolecular compound can be used as a part of fats and oils that constitute foods. Due to formation of the intermolecular compound, the fats and oils containing large amounts of symmetric triglycerides such as cocoa butter and those containing medium chain fatty acids do not form separate crystals and, therefore, can keep smooth texture and prevent blooming.
